June 13, 1933. G. w. JARDINE COLLAPSIBLE TUBE Filed Aug. 13, I932 Georye14 z'fardzize /I Home y Patented June 13, 1933 UNITED STATES GEORGE W.JABDINE, OF WALTHAM, MASSACHUSETTS COLLAPSIBLE TUBE Application fledAugust 13, 1932. Serial No. 828,747.

The present invention relates to new and useful improvements incontainers of the collapsible tube type and has for its primary objectto provide, in a manner as hereinafter set forth, a container of thischaracter having a novel closure which ishingedly mounted on saidcontainer to prevent loss thereof, said closure embodying a novelconstruction for releasably securing the same in closed position andfurther including means through the medium of which the container willbe sealed and leakage prevented.

Other objects of the invention are to provide a collapsible tube whichwill be simple in construction, strong, durable, attractive inappearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advanta es of theinvention will 9 become apparent rom a study of the followingspecification, taken in connection with theaccompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and

wherein Figure 1 is a view in top plan, showing a collapsible tubeconstructed in accordance with the present invention.

Figure 2 is a view in vertical section, taken substantially on the line2-.2 of Figure 1.

Figure 3 is a view in horizontal section, taken substantially on theline 3-3 of Figure 2. I

Figure 4 is an elevational View, showing the latching means for theclosure.

Figure 5 is an elevational view, showing the closure hinge.

Referring now to the drawing in detail, it will be seen that thereference numeral 1 designates the upper portion of a collapsible tubehaving a substantially conical shoulder 2 from which an integral neck 3rises.

The reference numeral 4 designates a cap which is hingedly mounted, asat 5, on the neck 3. The hinge 5 is sufficiently tight to frictionallyprevent idle swinging movement of the cap 4, as when said cap is in openposition. The cap 4 includes a depending skirt portion 6 whlch, when thecap is in closed position, encircles the upper end portlon of the neck3. A sealing gasket 7, of suitable resilient material, pre erably rubberor cork, is mounted in the cap 4 for engagement with the upper end ofthe neck 3 when said cap is in closed position.

Depending from the skirt 6 of the cap 4 is an arcuate latch 8 which issubstantially U- shaped in vertical section. The latch 8 terminates, atits free end, in an outwardly projecting lip constituting a releasinghandle 9 for engagement by the thumb or finger.

The neck 3 has formed therein a circumferentially extending groove 10for the reception of the latch 8. The latch 8 is of sufficient length topositively prevent rocking of the cap 4 on the neck 3 when said latch isengaged in the groove 10. This constitutes an essential feature of thepresent invention. Further, the end walls of the groove 10 extend at anacute angle relative to the inner wall of said groove (see Fig. 3) andthe sides of the latch 8 abut said end walls when the cap is in closedposition, as best seen in Fig.

4 of the drawing, thus positively retaining the cap against lateralswinging movement on its hinge 5 when said cap 1s in closed position.

In use, the latch 8 is disengaged from the groove 10 by exerting upwardpressure on the handle 9, after which the cap 4 may, of so course, beswung to open position. When the cap 4 is swung to closed position, thelatch 8 rides over the upper end portion of the neck 3 and snaps intothe groove 10, as will be apparent.

It is believed that the many advantages of a collapsible tubeconstructed in accordance with the present invention will be readilyunderstood, and although the preferred embodiment of the invention is asillustrated 9 and described, it is to be understood that changes in thedetails of construction and in the combination and arrangement of partsmay beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is A collapsible tube comprising an upstanding neckhaving a circumferentially extending groove therein, the end walls ofthe groove extending at an acute angle relative to the inner wall ofsaid groove, a cap hingedly mounted on the neck and including adepending skirt portion, an arcuate latch of substantially U-shapedvertical section depending 5 from the skirt and engageable in the groovefor securing the cap in closed position, the sides of the latch abuttingthe end Walls of the groove When the cap is in closed position, and alip projecting horizontally from the free end of the latch, said lipconstituting a handle.

In testimony whereof I afiix my signature.

GEORGE W. JARDINE.
